Grey Coated Wire Mesh is an industrial and construction wire mesh product made of high-quality metal wire as the base material, which is woven, welded, or stamped and then coated with a grey coating. With its characteristics of corrosion and rust resistance, strong weather resistance, high strength, uniform appearance, and excellent cost performance, it is widely used in building protection, fencing, industrial filtration, machinery protection, agriculture and animal husbandry, municipal engineering, slope reinforcement, and new energy infrastructure.
Raw materials are fundamental to determining the strength, toughness, corrosion resistance, and service life of Grey Coated Wire Mesh. The factory can provide a variety of base materials to choose from based on the customer's usage environment, cost budget, and engineering standards.
Q195 Low Carbon Steel Wire: Suitable for indoor use, dry environments, general fencing, aquaculture netting, and packaging netting. It is low in cost, has good plasticity, is easy to weld, and easy to weave, making it suitable for projects with general corrosion resistance requirements.
Q235 High Carbon Steel Wire: Suitable for construction scaffolding netting, protective netting, load-bearing netting, and machinery protection. It has higher strength, better tensile strength, and is less prone to deformation, making it suitable for applications with high stress and structural support.
For use in harsh environments with Grey Coated Wire Mesh, customized galvanizing processes are available:
Electro-galvanized wire: Thinner zinc layer, moderate cost, suitable for indoor use, short-term applications, and light corrosion protection needs;
Hot-dip galvanized wire: Zinc layer thickness up to 60–120 g/m², longer salt spray test duration, suitable for outdoor and humid environments. Zinc coating weights of 30g/60g/80g/100g/120g can be customized.
Customers can specify material standards, tensile strength, elongation, zinc layer weight, and material testing reports. The factory can provide material certificates, SGS reports, and factory warranty certificates.
The wire diameter directly determines the hardness, impact resistance, tensile strength, and service life of Grey Coated Wire Mesh, making it one of the most critical customization parameters in engineering procurement. Standard wire diameters are 0.5mm – 5.0mm, engineering-reinforced 5.0mm – 8.0mm, and precision fine mesh 0.3mm – 1.0mm. Different wire diameters also have different applications: 0.6mm / 0.8mm / 1.0mm are used for filtration, insect control, aquaculture, and window screens; 1.2mm / 1.5mm / 1.8mm are used for fencing, protection, and aquaculture cages; 2.0mm / 2.5mm / 3.0mm are used for building protection, highway fencing, and equipment enclosures; 3.5mm / 4.0mm / 5.0mm are used for heavy-duty protective netting, prison fencing, and bridge protection; and 6.0mm+ are used for special load-bearing netting, mine reinforcement, and mechanical protective structural components. Customers can specify wire diameter tolerances for applications such as automated equipment, precision filtration, and mold fitting.
The mesh size is crucial to the functionality of Grey Coated Wire Mesh. Different mesh sizes determine the protection level, ventilation, light transmission, filtration accuracy, anti-climbing capability, and installation effectiveness.
Mesh size customization range: Micro mesh: 2mm × 2mm / 3mm × 3mm / 5mm × 5mm; Standard mesh: 10mm × 10mm / 15×15 / 20×20 / 25×25 / 30×30 / 40×40 / 50×50mm; Engineering large mesh: 60×60 / 80×80 / 100×100 / 150×150mm; Rectangular mesh: 10×20 / 15×30 / 20×40 / 30×60 / 50×100 / 100×200mm;
Customizable mesh shapes: Square mesh is the most common, providing even stress and stable protection; rectangular mesh offers better ventilation and light transmission, saving materials; diamond mesh boasts high strength and structural stability, suitable for heavy-duty protection; hexagonal mesh is ideal for aquaculture, isolation, and slope protection, offering good flexibility; irregularly shaped meshes can be customized according to customer drawings, including plum blossom holes, elliptical holes, and elongated holes;
Customizable mesh precision: Standard precision ±0.5mm, engineering precision ±0.3mm, precision filtration precision ±0.1mm, suitable for high-precision applications such as screening, filtration, grading, mechanical limiters, and automotive parts.
Grey Coated Wire Mesh offers various structures to suit different applications. The factory supports customization of multiple structures including weaving, welding, stamping, stretching, and expanded metal mesh.
Welded Mesh Customization: Cross-welded horizontal and vertical wires create a flat surface, robust structure, and resistance to weld breakage. Suitable for fencing, construction, aquaculture, underfloor heating, and protection. Weld strength, weld failure rate, and surface flatness can be customized.
Woven Mesh Customization: Crimped weave, twill weave, and plain weave offer good flexibility, high tensile strength, and resistance to breakage. Suitable for mining, slope protection, and screening. Weaving density, roll diameter, and flexibility can be customized.
Perforated Mesh Customization: Perforated from a single sheet of material, resulting in uniform mesh size and an attractive appearance. Used for decoration, filtration, sound insulation, and equipment panels. Hole spacing, diameter, and arrangement can be customized.
Grey coating is the core aesthetic and corrosion protection feature of Grey Coated Wire Mesh, and it can be fully customized in terms of coating material, color code, coating thickness, coating process, and corrosion resistance level.
Coating Material Customization: PE (Polyethylene) coating offers moderate cost, good flexibility, and general corrosion resistance, suitable for ordinary outdoor and indoor projects, and short-term projects. PVC (Polyvinyl Chloride) coating boasts strong adhesion, good weather resistance, and UV resistance, suitable for long-term outdoor use, fencing, and municipal engineering. Powder coating provides a uniform surface, high-end texture, and stronger corrosion resistance, suitable for high-end equipment, architectural decoration, and high-end export markets.
